Fox shock no spacers?

[Matty_moo85]

Hi All,
I have a Fox float x evol that feels quite harsh on the small bumps roots ruts etc. Im also not using all the travel over bigger stuff. The shock is a "custom tune" c2bs off a yeti sb6 which i have fitted to my Focus Sam after giving it a service. I have taken the spacer which from what i can tell is a 0.4. Can I ride the shock with no spacer at all to see how it feels or is a spacer of some kind needed for the piston bottom out ect. If it blows though then I can buy the next smallest spacer? Any info would be great. Thanks!

Fine to run without a spacer and yes, you can fit a smaller spacer. It might be that the tune for the yetti just doesn't work with the Focus leverage rate.

Hey,
Thanks yeah that's also what I'm thinking but for the cost $100 I thought it was worth a shot. Way better than the magura stock shock for pedaling and jumps just the small fast impact stuff I'm not super happy with currently

Hey man before you start ripping spacers out try dropping your pressure in small increments. For mine if it's harsh on the small stuff AND you aren't using the full travel I'd start with air reduction first. If it was not using full travel only but small bumps were fine then I would change the spacers.

Hey yeah will give that a go to but I am already at 30% sag so was not sure if it would help ?

This.

OEM shocks usually have the dampers, particularly the high-speed compression circuit custom tuned for the bikes' leverage curves, and swapping from one frame to another, even if the overall and stroke lengths are the same, can have the shock perfoming less than ideally. That said, OEM tunes are still only averaged out over the full spread of rider weights, so still aren't perfect for everyone. If playing around with spring chamber volume and thus spring rate doesn't fix the issues, a service by a suspension specialist is usually on the cards to properly tune the shock to both you and the bike.

If already at optimum sag and it's still harsh, then increasing chamber volume (removing spacers) is definitely worth a shot.The idea of volume spacers is to reduce the chamber volume to enable the spring pressure to increase at a higher rate and give more support deep in the shock stroke to resist bottoming out. The trade off can be reduced top stroke compliance, as each little bump uses a greater proportion of the air chamber stroke. Taking spacers out increases the spring chamber volume, the small bumps use less of the available chamber stroke for the same movement, thus less change in pressure for a more supple feel, the trade off is less deep stroke support, but if you're not using full travel anyway, then it's not a bad thing, and you'll get better performance through the shock's range barring a damper tune issue as noted at the top of the post.

Given you are already at 30% SAG I concur with @The Duckmeister.

Thanks guys hopefully I can get out this weekend of a bit of a ride and muck around with pressures and settings. I'm guessing if the rebound is too slow that would also effect the small bump? Ie not recovinging quick enough. I have set that back up as per the fox pressure chart and will start from scratch.
